Application: Chemical Pump

Problem: Water-powered pump is used to dispense fertilizers, disinfectants, chlorine, acids, soaps, pharmaceuticals & nutritional supplements in a wide range of settings. Internal components are exposed to a number of chemicals, and must resist corrosion & wear against stainless steel components within the pump.

Chemical pumpSolution:
RTP 100 Series polypropylene with PFPE.

Benefits:

  • Excellent wear resistance
  • Eliminates need for separate metal or plastic bearings
  • Improved coefficient of friction in moving components
  • Excellent chemical and corrosion resistance

 

 

Application: Conveyor Rollers

Problem: Food conveyor rollers used in food processing equipment need to withstand constant movement & must be easy to clean to reduce risk of contamination. Material used in the rollers needs to be approved for food contact & have excellent wear resistance.Converyor Rollers

Solution:
RTP 800 Series acetal with PTFE & silicone

Benefits:
• Improved wear resistance
• Excellent lubricity
• FDA compliant
• Chemical resistance to cleaning solutions

 

 

 

Application: Disposable Pump

Problem: Traditional metal pumps used in the food, dairy, chemical, medical and pharmaceutical industries face contamination issues, which create down-time for maintenance and high cleaning costs. Multiple material requirements include: wear resistance, maintaining low warpage and low creep at operating temperatures of 110°C (230°F), and low moisture absorption to minimize swelling.

Disposable PumpSolution: 

RTP 1300 Series polyphenylene sulfide glass fiber reinforced compound with PTFE

Benefits:

  • Excellent chemical resistance
  • No need for external lubricants
  • FDA compliant polymers and ingredients

 

Application: HVAC Gears

HVAC gearsProblem: Due to extreme temperature changes (-40 0c to 80 0c) gears were creating excessive noise leading to warranty issues.

Solution: RTP 200 series and 800 series with glass fiber and PTFE.

Benefits:

  • Noise reduction
  • Low friction
  • Improved wear resistance

 

 

Application: Micro Pump Gears

Problem: Chemically resistant materials need to pump a wide variety of fluids over a wide temperature range including: espresso, water, pesticides, carbonated drinks, & alcohol. Application requires high wear materials but cannot utilize micro pumpglass fiber.

Solution:

RTP 2200 Series Peek with carbon fiber, aramid fiber & PTFE

Benefits:
• Excellent chemical & corrosion resistance
• High strength
• Wear resistant
• High heat resistance – Many micro pumps operate at very high speeds creating high temperatures at the wear interface

 

 

Application:  Positive Displacement Transfer Pump

Problem: Pump must be light weight and capable of moving hydrocarbons & other chemicals in mining, agriculture, marine, chemical, petroleum, & transportation industries in a range of environmental conditions

pos transfer pumpSolution:

Impeller: RTP 1300 Series compound with carbon fiber, PTFE & PFPE

Impeller Housing: RTP 2200 Series compound with carbon fiber, PTFE & PFPE

Wiper Blade: RTP 2200 Series compound with PTFE

Benefits:

• High strength
